摘要
以蚜虫为试虫,采用浸渍法测定了8种增效剂单剂对乙酰甲胺磷、高效氯氰菊酯及吡虫啉的增效作用,筛选出3种增效剂单剂(NT、PEG、吐温-20),以不同比例进行两两复配,测定混合增效剂对3种杀虫剂的增效作用.结果如下:(1)所有增效剂单剂或混合增效荆中吐温-20和NT以1:1混合时对乙酰甲胺磷原药的增效比最高,为28.6534.(2)PEG和NT以1:2混合时对吡虫啉原药的增效比最高,为5.12084.(3)增效剂单剂吐温- 20对高效氯氰菊酯原药的增效作用最好,增效比为13.29251.
Syergism between 8 syn measured in Aphids by soak test, erg th ists and 3 pesticides (acephate, beta-cypermethrin, imidacloprid) was ree best synergists were choiced and mixed in different proportions. The result is as follows. (1)the best Syergism in all synergists and m mixture of T-20 and NT in the ratio of 1 : 1, and the RS is 28. 653 4. ixtu (2) re-synerg the best ists to acephate is Syergism in all synergists and mixture-synergists to imidacloprid is the mixture of PEG and NT in the ratio of 1 : 2, and the RS is 5. 120 84. (3)the best synergist to beta-cypermethrin is T-20, the RS is 13. 292 51.
